WHO confirms six bird flu cases in Indonesia (Reuters) Updated: 2006-05-17 15:38
JAKARTA - The World Health Organisation confirmed six more human cases
of bird flu infections in Indonesia on Wednesday, including five members of a
family whose case has triggered fears of human-to-human
transmission. "There are six confirmations. One from Surabaya
and five from Medan. One from Medan is still alive," said Sari Setiogi, the
WHO's Indonesia spokeswoman.
An outbreak of H5N1 bird flu involving up
to eight members of a family at Medan in North Sumatra province has worried
health agencies around the world but a Health Ministry official said on
Wednesday it was not a case of human-to-human transmission. "The spread was
through risk factors from poultry or other animals. There is no proof of human
to human," Nyoman Kandun, director-general of disease control, told Reuters.
"The world is watching us. We are not being hasty," he added.
Four
of the five family members have died and samples from a further three people
believed to be part of the family cluster of infections are still being tested.
The WHO has sent a team to the area near Medan. The agency said it was
on alert for signs the virus is mutating into one that can be easily transmitted
between people, a development that could signal the start of a pandemic in which
millions could die. Such a mutation could occur anywhere there is bird flu,
the WHO says.
Kandun said authorities were still trying to identify the
source of the virus in the cluster case in Kubu Simbelang village in Karo
regency, about 50 km (30 miles) south of Medan.
But an Indonesian
agriculture official who declined to be named told Reuters tests had shed no
light on the case.
"There is a big question mark. Blood samples from all
kinds of animals from chickens, ducks, geese, birds, pigs, cats and dogs turned
out negative so far. Manure has also been checked. The result is negative," the
Jakarta-based official said.
Some reports have suggested chicken manure
used as fertiliser might be the link. Infected birds can excrete large amounts
of the H5N1 virus and this can be one way it can spread to birds, and people.
The sixth of the cases confirmed on Wednesday was a 38-year-old catering
businesswoman from Surabaya who had dealt with live pigs and pork meat before
she died last week.
The latest deaths bring the number of Indonesians
who have died from bird flu to 30, by far the highest death rate in the world
this year from the disease.
Bird flu has killed 115 people worldwide,
the majority in east Asia, since reappearing in 2003. Virtually all the victims
caught the disease from poultry.
The H5N1 virus is endemic in much of
Indonesia. On Tuesday a senior Agriculture Ministry official said H5N1 had been
detected for the first time in poultry in remote eastern Papua
province.
